It's a quote from wikipedia which is usually ... but sometimes not - up to date.
"SLEC Holdings was created as the holding company of the Formula One companies in 1996 when Bernie Ecclestone transferred his ownership of Formula One businesses to his wife, Slavica Ecclestone, in preparation for a 1997 flotation ..."
But a lot has changed since then. It was sold off as we know.
The article is a financial history of who had what, when and how much they got for it. Sorry to say it makes F1 sound sort of like a worn out trollop ( that's a sex worker in contemporary speech) not that there's anything wrong em) it. From 1974 to till today. I can recommend it because I can understand it

Theres a lot of side deals and companies involved.
EDIT - Yeah I agree ISLAMATRON. The Canadian government was willing to put out big bucks so we could put up those little white lawn signs with the red maple leaf around the course. Never understood that. Most people know the Canadian Gran Prix happens in Canada ... but this time I appreciate tax dollars spent on my favorite sport.
